F. Hagemann, ated October 20, 1931. As in the Hagemann patent, the feeding mechanism is operated by a handle of the reciprocating lever type, but it will be obvious that other types of operating means are applicable.

As shown in the drawing, there is a supporting frame 5 for the feed assembly mounted within a casing B which provides a housing for the operative elements.
